Aluminum Blow Off Valve S Diverter Turbo BOV Boost Fit For Volkswagen fit for GTI fit for Jetta fit for Audi 1.8T 2.7T Without Logo BOV-1022. The Splitter valve is a remarkable valve that gives a combination of blow off and recirculation valve operation all at the same time and has been specifically designed for the many turbo engined applications that operate metered airflow management systems. This means you get all the noise of the blow off valve whilst retaining the compatibility with the recirculation requirements of the engine management system. Designed as a direct replacement for OEM diverter valves, it integrates seamlessly with factory ECU control logic. No aftermarket tuning is required for standard or mildly modified turbo setups. Precision-machined internals and sealed actuation mechanisms ensure consistent operation over extended use, minimizing the risk of pressure leaks or mechanical failure under demanding conditions., Manufacturer: TLVBFPG
